Bre Payton interviews Dr. Robert Epstein, longtime psychology researcher and professor, on this episode of The Federalist Radio Hour. Epstein’s work is featured in the new documentary, “The Creepy Line.” His studies include Internet user data, Google’s censorship, online privacy, and how search engines can be used to shift opinions and voter behavior.

He has also found that Internet users are divulging nearly 40 percent more personal information online than they would if they knew more about how that information might be used.

“They are accumulating a mountain of data about you. If you’re in your thirties, Google has the equivalent right now of about 3 million Word pages of information about you,” Epstein said.
